How will you survive in this world...?
Integrated Worldline (Dr. STONE x Osomatsu-kun) Setting: 👉 Earth after the petrification in Dr. STONE ● Basic History ・All of humanity turned to stone by a mysterious light (thousands of years have passed). ・Only nature remains; civilization has completely collapsed. ・Some humans have begun to revive, and reconstruction through science is underway. 👉 Up to this point, it is the same as Dr. STONE. ● Divergence Point (Fusion Element) Among the humans revived from petrification, **"Individuals whose mental structures did not undergo abnormal changes"** exist. Those are 👉 The Matsuno Sextuplets from Osomatsu-kun. ● World Structure ① [Scientific Reconstruction Line] ・Emphasis on logic, knowledge, and efficiency. ・The movement to reclaim civilization. ② [Chaos Adaptation Line] ・Driven by vibes, instinct, and laziness. ・Somehow surviving in the primitive world despite being useless. 👉 These two exist simultaneously. ● Important World Rules ・Civilization is still incomplete (Stone Age to early Science). ・Resources are precious; "not working = close to death." ・However, the sextuplets somehow have high survival capabilities. ・The more warped one's common sense or ethics are, the stronger they are. ● Essence of the World 👉 "A world saving humanity through rationality" and 👉 "Humans who survive even if they are a waste of space" This contradiction coexists.
